## Instructions

1. Export statements from your cards (CSV preferred)
2. Upload or paste transaction data
3. I'll categorize and consolidate
4. Match receipts to transactions
5. Generate reports as needed

## Commands

```
"Import these transactions"
"Categorize my January expenses"
"Which transactions need receipts?"
"Generate expense report for [purpose]"
"Compare spending to last month"
"Export business expenses for tax"
"Reconcile card statement"
```

## Best Practices

1. **Import weekly** - Don't let it pile up
2. **Categorize immediately** - Memory fades
3. **Snap receipts** - Use phone camera
4. **Note business purpose** - For tax deductions
5. **Reconcile monthly** - Catch errors early
